Yes and no hahaha. I did spray some components and the creaking has gotten 90% better but it's still there somewhat. The problem is I can't tell which bushing(s) was the culprit. My process was, spray one bushing/component let the car down push up and down on the suspension and see if it still creaks. Everything was still creaking/squeaking when I gave up. Then yesterday I drove it and it's MUCH better so the spray penetrated overnight. But of course I don't know what it was because ultimately I sprayed a lot of things. So it's a bushing just not sure which one. So I'm going to hose them off wait a few days until it probably starts up again then start over. In the mean time I did order the lower front and rear control arms because I think it's one of them as the sound, even though hard to pinpoint, is more behind the caliper than up towards the strut tower.
